2 Claims.

radical flanges and a sleeve member fixed on the cone and having a radial liange extending into the space between the flanges of the cup membei'. The invention further consists in the bearing and closure and in the parts and combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawing,

Fig. l is a longitudinal sectional View of a bearing and closure embodying my invention; and

Figs. 2, 3 and 4 are elevational views of the parts making up the closure.

In the drawing is illustrated a double row taper roller bearing, including a double cup I or outer bearing member having conical race- Ways 2 that taper toward the middle of the cup, two cones 3 or inner bearing members, each having a conical raceway 4 corresponding to one of the cup raceways 2, a series of conical bearing rollers 5 interposed between each pair of cone raceways 4 and cup raceways 2, and cages 6 for maintaining the spacing of the rollers. The cup is providedwith radial passageways 1 at its middle through Which'the bearing may be lubricated.

Each end of the cup is counterbored and against each internal shoulder 3 in the cup is seated the cornerl portion of an 4angular ring member 9 having a sleeve portion I0 pressed in the cup and a radial flange II extending inwardly almost to the periphery of the end portion of the cone 3. Telescopedinto said sleeve portion I is the sleeve portion I2 of a second angular ring member I3 which also has a radial flange I4. The outer face of said radial ange I4 of said second angular ring I3 and the outer end of the sleeve portion I0 of said rst ring 9 are flush with the end face I of the cup and the end face I6 of the cone.

Pressed onto the outer periphery of the cone. 3 is the sleeve portion I1 of an angular ring member I8 which has an outwardly projecting radial flange I9 extending into the space between the radial flange II vand. the radial flange I4. The width of the radial flange I4 of thev second cup ring member I3 is such that its inner periphery is spaced slightly from the outer periphery of the sleeve portion I1 of the cone ring member IB.

The annular ring members 9, I3 and I8 may be assembled and the complete enclosure pressed in place as a unit. The outer ring 9 is pressed into the cup and the ring I8 is rpressed onto the cone, the length of the sleeve portion I'I thereof being such as to insure the proper location of the radial flange I9.

As the cup ring members and the cone ring `member are rigidly mounted, the closure members at -the two ends of the bearing make the double row bearing self-contained for shipment Y purposes. The adjustment may be built into the bearing before shipment, so that the proper mounting of the bearing is greatly facilitated. The closure members are flush with the ends of the bearing, thus minimizing the danger of injury in handling. 'Ihe hardened end I5 of the cup is exposed for clamping against a seat, thus avoiding Wear on the softer closure members. 'Ihe bearing may be packed with grease before shipment, thus avoiding entry of foreign` matter during shipment. The closure is made of simple stamped parts, so that the manufacture thereof and the assembling thereof are simple and inexpensive. The bearing and closure members are mounted as a unit, instead of theseparate mounting of bearing and closure members commonly required.

What I claim is:

l. A closure for the end of a roller bearing comprising an angular ring for seating in the' end of the outer bearing member of said bearing, facing outwardly, a second inwardly facing angular ring nested in said first named angular ring, said angular rings having inwardly extending spaced radial flanges and an angular ring having a sleeve portion for pressing on the inner' bearing member and having a radial flange extending into the space between the radial flanges of said first and second named rings said sleeve portion of said third angular ring extending outwardly and being of such length that said ring is in proper position when the end of said sleeve is flush withthe outer face of said second ring.

v2. A self-contained bearing closure comprising an angular ring having a flange disposed radially and an outer peripheral flange, a second anthe peripheral flange of said rst ring and a radial flange at the end remote from the radial flange of said rst ring and a third angular ring having a radial flange disposed between the radial anges of said first two angular rings and an inner peripheral sleeve or ange, said sleeve being of such length that the radial flange of said third ring is properly positioned when the end of said sleeve is iiush with the outer face of one of said radial anges.
